Five hundred and four patients completed the 12-week treatment and some patients continued the treatment for 24 weeks. Results Both leflunomide and MTX could improve the symptoms,signs,and joint function,but there were no changes in X-ray observations of patients with rheumatoid arthritis. In the leflunomide group,the overall rates of effectiveness at 12 weeks and 24 weeks were 86.94% and 92.31% respectively; the rates of remarkable improvement were 64.95% and 79.81% respectively. In the MTX group,the overall rates of effectiveness at 12 weeks and 24 weeks were 84.04% and 83.15% respectively; the rates of remarkable improvement were 56.81% and 75.28% respectively. According to intent-to-treat analysis,the ACR 20% response rates at 12 weeks and 24 weeks in the leflunomide group were 62.54% and 67.18% respectively,compared with 60.08% and 61.32% respectively in MTX group. No statistical differences were shown in the efficacy between the two groups ( P >0.05). The adverse events in the leflunomide group were gastrointestinal symptoms,skin rash,alopecia,nervous system symptoms,decreased leukocyte count,and elevation of alanine aminotransferase (ALT). Most of these side effects were mild and transient. The incidence of adverse events in the leflunomide group was 16.84%,significantly lower than that in MTX group (28.17%,P =0.002).Conclusions Leflunomide is effective in the treatment of RA with less adverse events than MTX. Its efficacy is similar to MTX,but the incidence of adverse events and the rate of withdrawal due to adverse events were lower in the leflunomide group than in MTX group.展开更多

This has been possible through use of various conventional and biologic disease modifying anti-rheumatic drugs(DMARDs) which target disease pathogenesis at a molecular level. Cost and infection risk preclude regular use of biologics in resource-constrained settings. In therecent years, evidence has emerged that combination therapy with conventional DMARDs is not inferior to biologics in the management of RA and is a feasible cost-effective option.展开更多

ARAVA®(Leflunomide) is a pyrimidine synthesis inhibitor. The experimental study was conducted for 8 weeks. We have also assessed the side effects of the therapy on their liver, myocardium and kidney. Leflunomide therapy improved the course of the clinical and paraclinical parameters, but it did not cure the condition. The positive results in the joints were accompanied by many histological alterations. The experiment revealed the toxic visceral effects of Leflunomide on the liver, heart and kidney.展开更多

Methods:A randomized controlled clinical trial was performed. All the 159 participates with active RA were randomly assigned to the control group(80 cases) and EAA group(79 cases) using concealed random allocation method. In the control group, patients were medicated with leflunomide and methotrexate for 48 weeks; and patients in the EAA group were administrated with leflunomide, methotrexate plus EAA(30 g/d). At the time points of 0, 12, 24 and 48 weeks, the clinical outcome measures, including objective pain score, tenderness score, number of painful joints, number of swollen joints, health assessment questionnaire(HAQ) score for quality of life, levels of serum rheumatoid factor(RF), anti-cyclic citrullinated protein antibodies(CCP-Ab), erythrocyte sedimentation rate(ESR), C reactive protein(CRP), visual analogue score for pain(VAS), and the overall efficacy were detected and recorded. Results:The objective pain score, number of painful joints and ESR at 12 weeks, tenderness score and HAQ at 24 weeks, and the tenderness score, number of painfull joints, number of swollen joints, HAQ, CRP, RF and CCP-Ab at 48 weeks were significantly improved in the EAA group compared with the control group(P〈0.01 or P〈0.05). At 24 and 48 weeks, the overall efficacy of the EAA group was significantly higher than the control group(P〈0.01). There were significantly higher withdrawal rate of corticosteroids within 12 weeks post-treatment and lower incidence rate of adverse effects in the EAA group compared with the control group(P〈0.01 or P〈0.05). Conclusion:EAA plus methotrexate and leflunomide were more effective and safer than the routine use of methotrexate and leflunomide in the treatment of active RA.展开更多

文摘Rheumatoid arthritis(RA)is a chronic inflammatory disease characterized by synovitis and destruction of cartilage,promoted by sustained inflammation.However,current treatments remain unsatisfactory due to lacking of selective and effective strategies for alleviating inflammatory environments in RA joint.Inspired by neutrophil chemotaxis for inflammatory region,we therefore developed neutrophil-derived exosomes functionalized with sub-5 nm ultrasmall Prussian blue nanoparticles(uPB-Exo)via click chemistry,inheriting neutrophil-targeted biological molecules and owning excellent anti-inflammatory properties.uPB-Exo can selectively accumulate in activated fibroblast-like synoviocytes,subsequently neutralizing pro-inflammatory factors,scavenging reactive oxygen species,and alleviating inflammatory stress.In addition,uPB-Exo effectively targeted to inflammatory synovitis,penetrated deeply into the cartilage and real-time visualized inflamed joint through MRI system,leading to precise diagnosis of RA in vivo with high sensitivity and specificity.Particularly,uPB-Exo induced a cascade of anti-inflammatory events via Th17/Treg cell balance regulation,thereby significantly ameliorating joint damage.Therefore,nanoenzyme functionalized exosomes hold the great potential for enhanced treatment of RA in clinic.
文摘目的探讨小剂量来氟米特配合甲氨蝶呤治疗老年首发类风湿关节炎(rheumatoid arthritis,RA)患者的效果。方法选取2020年2月至2023年2月西安市第五医院收治的120例老年首发RA患者进行随机对照试验。采用随机数字表法将其分为配合组及参考组,各60例。配合组男37例,女23例,年龄(70.22±5.29)岁,体质量指数(body mass index,BMI)(22.87±1.55)kg/m^(2),病程(4.76±0.85)年。参考组男38例,女22例,年龄(70.31±5.34)岁,BMI(22.94±1.58)kg/m^(2),病程(4.82±0.87)年。参考组采用甲氨蝶呤治疗,配合组则于参考组的基础上采用小剂量来氟米特治疗。两组均治疗90 d。对比两组临床疗效,临床症状改善情况,治疗前后骨代谢指标水平和血清壳多糖酶3样蛋白1(chitinase 3-like protein1,CHI3L1)、可溶性基质裂解素2(soluble suppression of tumorigenicity 2,sST2)、白细胞介素-32(interleukin-32,IL-32)水平,不良反应。采用χ^(2)检验和t检验。结果配合组总有效率高于参考组[96.67%(58/60)比83.33%(50/60)](χ^(2)=5.926,P=0.015)。配合组关节压痛数目、关节肿胀数目分别为(5.23±1.05)个、(4.18±0.66)个,均少于参考组的(7.45±1.36)个、(6.39±0.82)个,晨僵时长为(34.58±4.68)min,短于参考组的(50.40±8.21)min,双手握力为(14.03±2.55)kPa,高于参考组的(11.28±2.09)kPa(t=10.008、16.263、12.967、6.461,均P<0.001)。治疗后,配合组骨钙素(bone gla protein,BGP)、骨保护素(osteoprotectin,OPG)及总Ⅰ型胶原氨基端延长肽(total type I collagen amino terminal extension peptide,T-PⅠNP)水平分别为(27.48±5.02)ng/L、(5.02±0.74)ng/L、(43.17±8.59)μg/L,均高于参考组的(24.16±4.19)ng/L、(4.45±0.66)ng/L、(36.92±7.33)μg/L(t=3.933、4.453、4.287,均P<0.001)。治疗后,配合组血清CHI3L1、sST2、IL-32水平分别为(50.82±6.12)μg/L、(28.45±4.11)μg/L、(14.32±2.01)ng/L,均低于参考组的(78.45±8.39)μg/L、(33.05±5.24)μg/L、(16.85±2.77)ng/L(t=20.609、5.350、5.726,均P<0.001)。两组不良反应发生率对比,差异无统计学意义(P>0.05)。结论小剂量来氟米特配合甲氨蝶呤应用于老年首发RA患者中的效果较佳,可改善患者骨代谢指标及血清CHI3L1、sST2、IL-32水平。
